NRF24L01 & HLK-pm01

[alb12]

Hello,
I have made a PCB for a relay with nrf24L01, attiny and HLK-PM01.
If I feed the pcb with the arduino, with 3v or 5v I have no problem, the relay switches but when the PCB feed whith the electric outlet the relay don't switch always.
I don't know what, maybe the radio signal of nrf24 dont received.

Have you an idea?

Thank you

Welcome to the MySensors community @alb12

The quickest way to see what is happening is to activate serial debug. The debug output will show what happens.

See https://www.mysensors.org/build/debug#enabling-debug-and-monitoring-the-logs for more detailed information.

Yes but I use an Attiny84 so I can't use the serial debug
